Jaltest JDC539A - Bobcat Diagnostic Y-Cable

The Jaltest JDC539A is a genuine Cojali diagnostic Y-cable for Bobcat construction equipment, agricultural tractors, and telehandlers. Bobcat Company (a Doosan Bobcat brand) manufactures some of the most widely used compact construction equipment in North America — skid steer loaders, compact track loaders, compact excavators, telehandlers, and utility equipment found on job sites everywhere. This Y-cable design provides the connection from the Jaltest Link to Bobcat equipment's diagnostic interface, working in conjunction with the Jaltest OHW software for full electronic access.

What This Cable Does

The JDC539A is a Y-cable, meaning it splits into two connectors at one end to accommodate Bobcat's specific diagnostic interface configuration. It connects the Jaltest Link to Bobcat compact equipment for fault code diagnostics, software updates, calibration work, and live data monitoring. The cable is equipped with a remote switch for easy operation during diagnostic sessions.

What the Y-Cable Design Means

Unlike simple single-connector diagnostic cables, the JDC539A uses a Y-cable configuration — two connectors that simultaneously interface with Bobcat's diagnostic system. This design accommodates the way Bobcat equipment routes diagnostic communication, allowing the Jaltest Link to properly establish the communication link. The integrated remote switch allows the technician to initiate the diagnostic connection without returning to the laptop or diagnostic interface, which is a practical convenience when working in tight spaces around compact equipment.
